Android NDK unable to debug native code with two gradle plugins

Question

I'm using NDK with the experimental gradle plugin, and initially I was able to debug my native code.

Then I saw this issue https://github.com/googlesamples/android-ndk/issues/119 and this blog post http://frogermcs.github.io/json-parsing-with-flatbuffers-in-android/. This approach would be great, because I could use the stable gradle plugin for android specific code, and the experimental gradle plugin for the native code, witch would be great to use use databinding for example. I was able to use this structure, but I lost the ability to debug native code.

I have created a sample project that illustrate my problem. https://github.com/4brunu/AndroidNDKDebug

In there you can find two projects. The first one "hello-jni-one-gradle-plugin", only use the experimental gradle plugin, and I'm able to debug the native code. The second one "hello-jni-two-gradle-plugins", I use the stable gradle plugin for android specific code, and the experimental gradle plugin for the native code, and I'm unable to debug the native code.

Am I doing something wrong? Could you help me enable native code debug in the second project please?

Thanks

I'm using the same setup in one of my projects, with Android Studio 2.1-preview5, gradle-experimental 0.7.0-alpha5, and gradle plugin 2.1.0-alpha5, and debugging works.

The secret missing step is to add the path to your non-stripped libs to the debugger: lib/build/intermediates/binaries/release/obj/ABI
